"value": "AV:L - The affected code is the Apple ANS2 SoC-internal NVMe platform driver; the vulnerable state is created during local device probe and reached afterwards through ordinary local syscalls (reading `/sys/class/nvme/nvmeN/*`, opening `/dev/nvmeN`). No network, adjacent-network, or physical-access path exists — the controller is on-die, so physical presence buys nothing.\nAC:H - The only branch reaching the buggy `put_dev` label after `nvme_init_ctrl()` succeeds is a `blk_mq_alloc_queue()` failure, i.e. a `GFP_KERNEL` allocation failure inside device probe — small GFP_KERNEL allocations do not fail on demand (they retry and invoke the OOM killer), and probe normally runs only at boot. The attacker cannot influence whether this precondition occurs.\nPR:L - Once the probe has failed and left the controller device registered over freed devm memory, the dangling object is reached with no privileges beyond an unprivileged local account: `/sys/class/nvme/nvmeN/` is world-traversable and `model`, `serial`, `firmware_rev`, `state`, `transport`, `subsysnqn`, `address`, `cntlid`, `queue_count` are all `S_IRUGO` with no capability check in their show handlers.\nUI:N - No victim action is required — the failing probe occurs on its own during boot under memory pressure, and the attacker simply reads the leaked sysfs attributes or opens the leaked device node.\nS:U - The corruption is confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free read of the `nvme_ctrl` embedded in the devres-freed `anv` block — `model_show`/`serial_show`/`firmware_rev_show` follow `ctrl->subsys` out of freed memory and `sysfs_emit()` the bytes straight to userspace, disclosing whatever kernel data has reclaimed that slab object.\nI:H - The still-registered device leaves function pointers (`ctrl->ops->get_address`, `ctrl->device->release`, the cdev's `f_op`) inside a freed slab block the attacker can reclaim and groom by spraying same-size allocations, and `nvme_sysfs_show_address()` performs an indirect call through one of them — a control-flow hijack primitive, with `reset_controller`/`delete_controller`/`passthru_err_log_enabled` stores writing into the freed object as well.\nA:H - Dereferencing the freed controller (`ctrl->subsys->model`, `ctrl->ops->get_address()`) oopses the kernel, and because the stale `/dev/nvmeN` and sysfs nodes persist for the lifetime of the boot the crash can be re-triggered at will by any local user; the unreleased ida instance, discard page, and srcu struct also leak on every occurrence."
